After upgrading, my computer will randomly freeze up completely while watching videos on Youtube. So far it's only doing this with Chrome. When I run Chrome via the terminal and go to Youtube, I get this message:
[WARNING:flash/platform/pepper/pep_module.cpp(63)] SANDBOXED ATTENTION: default value of option force_s3tc_enable overridden by environment.
I have no idea what this means. All I know is that I never had this problem in 13.04. Any help is appreciated.
